Bug#928899: giftrans FTCBFS: uses the wrong compiler

[Helmut Grohne <helmut@subdivi.de>]

Source: giftrans
Version: 1.12.2-19
Tags: patch
User: helmutg@debian.org
Usertags: rebootstrap

giftrans fails to cross build from source, because debian/rules uses the
build architecture compiler as a make default. The easiest way of fixing
that - seeding $(CC) from dpkg's buildtools.mk - makes giftrans cross
buildable. Please consider applying the attached patch.
